Encrypted phones

Secure Architecture from Chip to Cloud

The platform boots from a fused secure element that verifies every firmware block with cryptographic signatures. Storage is encrypted using AES-256 with keys locked inside the Trusted Execution Environment, while the radio stack runs in a sandbox isolated from user data. All outbound traffic passes through a double ratchet protocol that provides perfect forward secrecy; even if one session key is exposed, past and future conversations stay protected.

Core Security Functions

End-to-end encrypted voice and video — peer-to-peer keys generated on device, never stored on servers.
Ephemeral messaging — messages auto-delete on a timer and are wiped from flash using secure-erase commands.
Panic wipe — a duress PIN or multiple failed log-ins trigger instant zeroisation of all keys and user data.
Remote device revocation — administrators can disable or brick a lost handset via the management console.
Metadata-hiding transport — TLS obfuscation disguises signalling traffic as ordinary web sessions, reducing traffic-analysis risk.

Operational Workflow

Devices are provisioned in a clean room, where a one-time QR code pairs the handset with the customer’s secure key server. All further updates are signed and verified on device; sideloading and USB debugging stay disabled. When users call or text, keys are created client-side, exchanged via a brief Diffie–Hellman handshake and destroyed at session end. Attachments never transit in clear; files are AES-GCM encrypted with unique per-file keys before upload.

Typical Applications

Corporate board communications — secure strategy calls that must remain off record.
Law-enforcement task forces — deconfliction chat channels during sensitive operations.
Journalists in hostile regions — protect sources with self-erasing messages.
Diplomatic missions — guarantee confidentiality over foreign networks.
Critical-infrastructure operators — isolate SCADA incident reports from public carrier services.

Frequently Asked Questions

Can the vendor read my data?
No. End-to-end keys are generated exclusively on the handset; servers handle routing but never possess decryption material.

What happens if the phone is seized?
Without the unlock secret the secure element withholds keys; after preset attempts the device zeroises itself, rendering data unrecoverable.

Does it support regular SIM cards?
Yes, but all voice and SMS traffic outside the secure app travels unencrypted; security applies to calls and messages placed through the encrypted suite.

How are software updates delivered?
Updates are signed by the manufacturer’s offline key and verified by the bootloader; unsigned packages are rejected automatically.

Regulatory & Compliance Notes

Export of strong cryptography is governed by EU Dual-Use category 5A002. Commercial buyers must provide an end-user statement confirming lawful use. Devices include a compliance log so auditors can verify that cryptographic modules remain unmodified throughout their service life.

Communicate Confidently—Wherever You Operate

Standard smartphones expose sensitive conversations to carrier logs, cloud backups and physical seizure. An encrypted phone mitigates each of those vectors with hardware-anchored trust and provable end-to-end encryption, letting you speak, text and share files knowing your confidentiality rests on mathematics—not on promises.
